I've read a number of threads on here about way wiper design and construction, and after much hemming and hawing, I finally ordered several meters of Kabelschlepp standard design (BA18) to build wipers for the old Rockford(/Hedwick/Logan/Fendlind) MV100 mill that I'm restoring. Sadly, that machine never came with wipers, straight from the factory, which explains the sorry state of the ways...
So, quoting Forrest from an old thread --
"Ideally a way wiper system features triple protection. A stiff brass overlying protector protects against chips pile-ups. It should be backed by a thinner brass inner scraper tensioned against the way at an angle to push debris ahead something like a putty knife. The inner scraper should be flexible enough to allow trapped debris to roll underneath with the axis element is going away from the wiper. Backing the scraper and the protector is the molded rubber wiper which is lightly tensioned against the way. Backing THAT up is a felt wiper designed to spread lubricant and to catch any fines the wiper misses." -- Forrest Addy
The Kabelschlepps will give me the middle piece, squeegying the way clean. I have some reasonable copper flashing to make up the top layer (24 gauge), along with a nice little Di-Acro finger brake to fold that copper up. My question is this: what do I do for the other two layers? Brass shim stock for the way scraper ahead of the Kabelschlepp? How thick?
With the Kabelschlepp bolted to the saddle or knee, how would I set up something like felt wiper behind? Or should I skip that component altogether?
Finally, given that there are no original holes to match to on the machine, since it never had wipers, how should I locate holes to preload the Kabelschlepp against the way properly?
Thanks,
Will
